Release 05 Revision History
Known compatibility issues
·
Requires version 3.31 or later of editing software.
·
Requires v2.06 or later of Emerald.dll.
05x00 - 30/01/09 - Changes from Release 04
·
Added Round Bitmap Tacho Gauge. This allows the pointer positions and offsets to be
specified but does not draw any part of the gauge other than the pointer. It also allows a bitmap
to be specified as the background thus allowing quite sophisticated gauges to be drawn.
·
Added Odometer output.
·
Add an extra lower limit section to bar tachos that can be set to be a different colour. The new
bar tacho also supports a flashing mode that if the upper and/or lower limits are passed, the
limit section or the entire bar can be flashed. Current flashing frequency is 1Hz.
·
Support added for second serial comms channel on LDS4. LDS4 now has dedicated SMS1
support on Serial 1 and serial data stream support on Serial 2.
05x02 - 11/02/09
·
Added a fast CAN transmit - this sends out the first 4 analogue inputs at 1kHz, big endian on
message 0x700.
·
Analogue 3 is mapped as up/down button and can be used as a push button page select.
05x03 - 12/02/09
·
Added support for real time clock in LDS4 Issue B boards.
·
reduced the number of available CAN messages to 31 to protect the fast CAN Tx added in #78.
If more channels are required, specify an appropriate CAN mask in LDS4Editor.
·
LDS4 Analogue 2 now used for up/ down button as per CD24.
05x04 - 24/03/09
·
Added support for serial GPS data streams in standard NMEA format.
·
Added on-board sector analysis. This uses GPS from a serial link to determine the car position
on-track.
·
Made the OSA sector tolerance programmable. By default this is set to 0.003 minutes
(about +/- 6m).
·
Added ability to display negative time information eg for split time differences.
·
Fixed a bug that could erroneously trigger a lap start on power on.
·
Interpolates latitude and longitude between GPS updates if a valid speed and heading are
present.
·
Added support for GPS signals via CAN.
·
Added a GPS Output that shows the GPS parameters (such as lat long etc) in a unified format.
·
Written a StrToInt function for faster processing of GPS serial streams.
